Image capture device, image capture method, and image capture system

Abstract

Provided is an image capture device capable of achieving both high resolution of images and high frame rate. An image capture device 10 takes images and outputs image data, and includes region of interest compression means 11 for performing lossy compression processing on pixel data of a region of interest and outputting the pixel data.

What is claimed is: 
     
       1. An image capture method performed by a computing device of a system including a plurality of image capture devices and a wide area imaging device having a wider angle of view than that of the plurality of image capture devices, the image capturing method comprising:
 positionally identifying a region of interest, based on an image captured by the wide area imaging device; 
 determining, among images captured by the plurality of image capture devices, an image in which lossy compression processing is to be performed on the region of interest, based on the image captured by the wide area imaging device; and 
 causing the image capture device that captured the determined image to perform lossy compression processing on pixel data of the region of interest in the determined image, including indicating the identified region of interest to the image capture device that captured the determined image, wherein 
 only the image capture device that captured the determined image performs the lossy compression processing on the pixel data of the region of interest. 
 
     
     
       2. The image capture method according to  claim 1 , wherein
 the lossy compression processing of a predetermined specific method type is performed on the pixel data of the region of interest whose having a fixed size. 
 
     
     
       3. An image capture system comprising:
 a plurality of image capture devices that are each configured to perform lossy compression processing; 
 a wide area imaging device having a wider angle of view than that of the image capture-device the plurality of image capture devices; and 
 a processor; and 
 a memory storing instructions executable by the processor to: 
 positionally identify a region of interest, based on an image captured by the wide area imaging device; 
 determine, among images captured by the plurality of image capture devices, an image in which lossy compression processing is to be performed on the region of interest, based on the image captured by the wide area imaging device; and 
 cause the image capture device that captured the determined image to perform lossy compression processing on pixel data of the region of interest in the determined image, including indicating the identified region of interest to the image capture device that captured the determined image, wherein 
 only the image capture device that captured the determined image performs the lossy compression processing on the pixel data of the region of interest. 
 
     
     
       4. The image capture system according to  claim 3 , wherein the processor positionally identifies the region of interest based on a position of an eye of a person in the image captured by the wide area imaging device. 
     
     
       5. The image capture system according to  claim 3 , wherein
 the lossy compression processing of a predetermined specific type is performed on the pixel data of the region of interest having a fixed size.
